Isingeniso sokusetjenziswa, izinto eziqakathekileko kanye nobujamo be-wafer check valve

Hlola ivalvu kutjho i-valve evula begodu ivale ngokuzenzakalelayo i-valve flap ngokuthembela ekugelezeni kwe-medium ngokwayo ukukhandela ukugeleza emuva kwe-medium, eyaziwa nangokuthiivalvu yokuhlola, ivalvu yendlela eyodwa, ivalvu yokugeleza emuva kanye nevalvu yokugandeleleka emuva. Iivalvu yokuhlolayivalvu ezenzakalelayo umsebenzi wayo omkhulu ukukhandela ukugeleza emuva kwe-medium, ukujikeleza emuva kwepompo ne-motor etjhayelako, nokukhutjhwa kwe-medium ngaphakathi kwekhonteyina. Amavalvu wokuhlola angasetjenziswa godu emigqeni enikela ngeenhlelo ezisizako lapho umfutho ungakhuphuka ngaphezu komfutho wesistimu.

1.Tukusetjenziswa kwevalvu yokuhlola i-wafer:

Iivalvu yokuhlola ifakwe erherhweni lamapayipi, begodu umsebenzi wayo omkhulu kukhandela ukubuyela emuva kwe-medium. Iivalvu yokuhlolayivalvu ezenzakalelako evulwa begodu ivalwe ngokuya ngomfutho ophakathi.Ivalvu yokuhlola i-wafer ilungele ukugandeleleka kwe-PN1.0MPa~42.0MPa, iKlasi150~25000; ububanzi obubizwako DN15~1200mm, NPS1/2~48; Ukubuyela emuva okuphakathi. Ngokukhetha izinto ezihlukahlukeneko, ingasetjenziswa eendaweni ezihlukahlukeneko ezifana namanzi, umtjhiso, amafutha, i-nitric acid, i-acetic acid, i-oksidizi eqinileko kanye ne-uric acid.

2.Tinto ekulu yeivalvu yokuhlola i-wafer:

Kune-carbon steel, i-low temperature steel, i-dual phase steel (F51/F55), i-titanium alloy, i-aluminium bronze, i-INCONEL, i-SS304, i-SS304L, i-SS316, i-SS316L, i-chrome molybdenum steel, i-Monel (400/500), i-Hastelloy nezinye izinto.

3. Iimpawu zesakhiwo seivalvu yokuhlola i-wafer:

A. Ubude besakhiwo bufitjhani, begodu ubude besakhiwo buyi-1/4 ~ 1/8 ye-valve yokuhlola ye-flange yendabuko

B. Ubukhulu obuncani nobudisi obulula, ubudisi bayo buyi-1/4 ~ 1/20 ye-valve yokuhlola ye-flange yendabuko

C. Idiski yevalvu ivala msinyana begodu umfutho wesando samanzi mncani

D. Amapayipi avundlileko nofana athe ngqo angasetjenziswa, kulula ukuwafaka

E. Itjhaneli yokugeleza ibutjhelelezi begodu ukujamelana kwe-fluid kuncani

F. Isenzo esibucayi nokusebenza okuhle kokuvala

G. Ukukhamba kwe-valve disc kufitjhani begodu amandla wokuvala womthelela mancani

H. Isakhiwo soke silula begodu sincani, begodu ijamo lihle

I. Isikhathi eside sokusebenza nokusebenza okuthembekileko

4.TAmaphutha avamileko we-valve yokuhlola:

A. Idiski yevalvu iphukile

Umfutho we-medium ngaphambi nangemva kwevalvu yokuhlola usebujameni bokutjhidela ekulinganiseni kanye "nesaha" elifanako. Idiskhi yevalvu ivamise ukubethwa ngesihlalo sevalvu, begodu idiski yevalvu eyenziwe ngezinto eziphukileko (njengesimbi, ithusi, njll.) iyaphuka. Indlela yokuvikela kukusebenzisa i-valve yokuhlola ene-disc njengento ethambileko.

B. Ukubuyela emuva okuphakathi

Indawo yokuvala ilimele; ukungcola kuvalelekile. Ngokulungisa indawo yokuvala nokuhlanza ukungcola, ukugeleza emuva kungavinjelwa.
